Answer:p = 28.36

q = 31.78

Step-by-step explanation:

Considering the smaller right angle triangle, with 50° as the reference angle, the opposite side is q and the adjacent side is 55 - p

Applying the tangent trigonometric ratio which is expressed as

Tan θ = opposite side/adjacent side

Tan 50 = q/(55 - p)

1.1918(55 - p) = q - - - - - - - - - 1

Considering the bigger right angle triangle, with 30° as the reference angle, the opposite side is q and the adjacent side is 55

Applying the tangent trigonometric ratio which is expressed as

Tan θ = opposite side/adjacent side

Tan 30 = q/55

0.5774 = q/55

q = 55 × 0.5774

q = 31.757

Substituting q = 31.757 into equation 1, it becomes

1.1918(55 - p) = 31.757

65.549 - 1.1918p = 31.757

1.1918p = 65.549 - 31.757

1.1918p = 33.792

p = 33.792/1.1918

p = 28.36

A production process is checked periodically by a quality control inspector. the inspector selects simple random samples of 30 f

777dan777 [17]

Answer:

Population Mean = 2.0

Population Standard deviation = 0.03

Step-by-step explanation:

We are given that the inspector selects simple random samples of 30 finished products and computes the sample mean product weight.

Also, test results over a long period of time show that 5% of the values are over 2.1 pounds and 5% are under 1.9 pounds.

Now, mean of the population is given the average of two extreme boundaries because mean lies exactly in the middle of the distribution.

So, Mean, $\mu$ = $\frac{1.9+2.1}{2}$ = 2.0

Therefore, mean for the population of products produced with this process is 2.

Since, we are given that 5% of the values are under 1.9 pounds so we will calculate the z score value corresponding to a probability of 5% i.e.

z = -1.6449 {from z % table}

We know that z formula is given by ;

$Z = \frac{Xbar - \mu}{\frac{\sigma}{\sqrt{n} } }$ ~ N(0,1)

-1.6449 = $\frac{1.9 - 2.0}{\frac{\sigma}{\sqrt{n} } }$ ⇒ $\frac{\sigma}{\sqrt{n} } = \frac{-0.1}{-1.6449}$

⇒ $\sigma =$ 0.0608 * $\sqrt{30}$ {as sample size is given 30}

⇒ $\sigma$ = 0.03 .

Therefore, Standard deviation for the population of products produced with this process is 0.0333.

Want 100 Points??? Then plz help me on my HW. A grocery store advertises cherries on sale for $2 per pound. At a different store

quester [9]

11 / 2.75 = 4

2 * 2.75 = 5.5

11 - 5.5 = 5.5.

Milliw paid $5.50 more than she would have if she bought them on sale. The work should explain the answer. She spent $11 on 2.75 lbs of cheeries when she could've spent half of that on cherries which were on sale.
